Struct Rule 

pub struct Rule {
    pub rules: Arc<RwLock<HashMap<String, Box<dyn Generator>>>>,
    pub name: String,
}

Rule is a Generator for invoking a named rule Generator. This is useful for implementing recursion and avoiding duplication of portions of a grammar.

Only names that have already been registered should be used. If a corresponding rule does not exist when generate is called it will panic.

Fields

rules: Arc<RwLock<HashMap<String, Box<dyn Generator>>>>

name: String
